We know who they are.

I mean, some of them aren't really in the public eye, but they are definitely far from secret

Example from Texas:
https://www.texasobserver.org/hard-right-megadonors-tim-dunn-and-farris-wilks-pump-millions-into-gop-primary-wars/
For more than a decade, the two West Texas oil and gas moguls have used their fortunes to finance an ideological crusade to oust the torchbearers of the party establishment and install champions of their far-right, theocratic agenda.
...
Dunn and Co. aren’t stopping at the statewide primaries. They’ve historically had the most electoral success by putting up big money behind challengers—and tarring GOP incumbents as liberal hacks—in state House and Senate races.

Hours before the Texas House overwhelmingly voted to impeach Ken Paxton in May, a well-funded supporter of the attorney general issued a threat to his fellow Republicans.
A vote to impeach Paxton, Jonathan Stickland wrote on Twitter, “is a decision to have a primary.”
"Wait till you see my PAC budget,” he later added.
Stickland is the leader of Defend Texas Liberty, a political action committee that has donated millions of dollars to far-right candidates in the state. It is a key part of the constellation of political campaigns, institutions and dark-money groups that a trio of West Texas oil tycoons — Tim Dunn and brothers Farris and Dan Wilks— have pumped small fortunes into as part of a long-term crusade to push Texas to the extreme right.

Not just that, they actively support and celebrate these people.

- Yeah I know. The visible ones are those who made it by working hard and we should support them by demanding lower taxes.
  But you got the part about minorities wrong. The invisible ones make them move to our countries by HAARP and chemtrails (some even turn to gay frogs on the way!) to steal the moldy apartments and the 10 bucks per hour crap jobs we have.

Yep, Federalist Society buying judges being a prime example that almost anyone that's politically involved can think of off the top of their heads. They don't need to hide it unless it's literally child prostitution or something similar, they can just do it out in the open because the average mook is too busy trying not to be homeless to care.

Just the way they designed society. It's also why they oppose social safety nets, worker-owned co-ops, anything socialist / communist, universal basic income, helping house and feed the homeless, free or low cost higher education, etc.

Don't want people to actually have power and self-determination.

Gee I wonder who would want to start a rumor like that?

They aren't Jewish enough

Yeah, "fun" and not horribly depressing.

The problem isn't that they think they are super wealthy and controlling everything. The problem is they think they are jewish and controlling everything.

Is it possible to be rich in secret?

and more fundamental, do rich people discose their wealth themselves? how can we confirm that what they say is accurate?

The part about their methodology might answer your questions to a degree.
- thank you!
